Though about 2000-3000mm rainfall, frequent and severe drinking water shortage in many wadis. This year, about 25 wadis are dry since april.

I 40 liters per person per day within 1.5 km. About 40 wadis dry today, esp. in the north Karjat area. South Karjat served by the tail-water of Hydel station through Pej river.

Objectives To make Karjat taluka drinking water secure To design a series of interventions: technical, administrative, policy.

I Pilot studies and pilot implementations
